Title: Pseudo high speed photographing method
Inventor: UMETSU SEIJI
IPC: H04N5/378
Filed: 1995-03-31
Abstract: PURPOSE: To attain the same photographing as high speed video inexpensively and simply by providing an electronic circuit for controlling to a light source for emitting and controlling emitting time conditions such as an emitting time of a light source for emitting and a delay time interval delaying an emitting time. CONSTITUTION: When the input of initial setting for a control program is finished, an operation of an automatic variable delay device 2 is started. An electronic circuit section starts to fetch an electric signal immediately before a diesel nozzle 1 ejects fuel. This signal is sent to a microcomputer, and a delay circuit is controlled with procedure set by a control program previously prepared. As for the output of the delay circuit, a previously set delay time is varied automatically and successively, and the output signal is sent to a light source 3. Whenever a signal is received, the light source 3 lights, and a diesel atomizer 4 is irradiated. Since a lighting start time after atomization in every time of atomization is made longer by a delay time interval, atomization is grasped as if it is slowly developed by performing photographing and the like in a darkroom.

Title: Erasing device of electrophotographic copier
Inventor: KATSUMATA AKIO
IPC: G03G21/08
Filed: 1984-04-18
Abstract: PURPOSE:To make control of timing of lighting of an erasing lamp easy and to simplify the device by making driving circuits common by equalizing the distance from the position of incidence of an original light image to a photosensitive body in two photosensitive bodies. CONSTITUTION:When the distance from the position of incidence of an original image to an erasing device is different in two photosensitive bodies, the time from exposure of the front end or rear end of the picture to arrival at the erasing position is different depending on photosensitive bodies. Accordingly, two erasing devices must be controlled in terms of turning on and off at separate timing to make the control complicated. Further, driving elements must be provided separately. Therefore, an exposing device and an erasing device are so arranged to equalize the distance l1 from the position of exposure 10 in a photosensitive drum 6 to the erasing device 11 and the distance l2 from the position of exposure 17 in a photosensitive drum 7 to the erasing device 18.

Filed: 1990-03-28
Abstract: PURPOSE:To realize a transmission type screen that has a large angle of visual field in horizontal and vertical directions and moire is not generated by arranging lenticular lenses on a concentric circle. CONSTITUTION:The observing surface side of the transmission type screen 1 that a Fresnel lens 2 is formed on the light incident surface side thereof is constituted of the circular lenticular lens 4 that many fine cylindrical lenses 4 are successively formed on the concentric circle which coincides with the center of the lens 2. Thus, by making the arrangement of the lenses 4 quite axially symmetric with respect to the central axis of the screen, light emitted from the screen is diffused in every direction such as top and bottom and left and right and the angle of the visual field can be enlarged not only in the horizontal direction but also in the vertical direction. Besides, by arranging the lens 4 on the concentric circle which coincides with the center of the lens 2, directional difference between both lenses is eliminated and the occurrence of the moire is restrained.

Abstract: PURPOSE:To correctly execute the detection of a Z phase signal by detecting a fact that a moving body arrives in the vicinity of an origin position, and thereafter, setting a detecting position of the next Z phase signal on an origin after passing through a set value of a moving amount. CONSTITUTION:To a positioning control part 7 for driving a servomotor M, a present position managing part 8 for integrating a detecting signal of an encoder E and managing the present position against a reference position (origin) is connected. In such a state, after an origin LS 6 is turned off, a Z phase signal detection command part 11 outputs a Z phase detection command to a Z phase signal detecting part 13 after passing through a value (a) set by a Z phase non-detection amount setting part 12. During this time, the present position managing part 8 integrates the detecting signal of the encoder, based on the time point of turning off the origin LS as a reference, and derives a moving amount of a moving body. Also, after the origin LS is turned off, the Z phase signal detecting part 13 detects a Z phase signal at a distance (a) set by a parameter, stops at an origin position X0, and the present position managing part 8 sets this position X0 as an origin. In such a way, the Z phase signal is detected stably.
